1.Introduction:
(1) Weathering steel: Weathering steel is also called atmospheric corrosion-resistant steel. It is a series of low-alloy steel between ordinary steel and stainless steel, its corrosion resistance is also between the two; weathering steel from plain carbon steel with a small amount of copper, nickel and other corrosion-resistant elements.
(2) Manganese steel: Manganese steel is the collective name of manganese alloy steel, specifically: 16 manganese steel, high manganese steel, etc.. If 2.5-3.5% of manganese is added to the steel, then the resulting low manganese steel is simply as brittle as glass, a knock on the broken. However, if you add more than 13% of manganese, made of high manganese steel, then it becomes both hard and tough. Usually high manganese steel (wear-resistant steel) refers to the manganese content of more than 10% of the alloy steel, such steel containing 10% to 15% manganese, high carbon content, generally 0.90% to 1.50%, most in 1.0% or more. When high manganese steel is heated to light orange, it becomes very soft and easy to carry out various processing.
2. Characteristics:
(1) Weathering steel: It has the characteristics of high quality steel, such as strong, plastic extension, forming, welding, abrasion, high temperature, fatigue resistance; at the same time, it has the characteristics of rust resistance, so that the members of corrosion resistance to extend life, thinning and energy saving.
(2) Manganese steel: It is not magnetic and will not be attracted by magnets.
3. Applications:
(1) Weathering steel: Weathering steel is mainly used for steel structures used in railways, vehicles, bridges, towers, photovoltaic, high-speed engineering and other long-term exposure to the atmosphere. Used in the manufacture of containers, railway vehicles, oil derricks, harbor buildings, oil recovery platforms and chemical and petroleum equipment containing hydrogen sulfide corrosive media in the container and other structural components.
(2) Manganese steel: People use a lot of manganese steel to make steel mills, ball bearings, buckets of bulldozers and earth-moving machines and other components that are often subject to wear, as well as railway tracks and bridges.
4. Subordinate branches:
(1) Weathering steel: Weathering steel is not a branch of stainless steel, is a new steel bell. The principle of stainless steel corrosion is to keep the steel from rusting, however weathering steel is to let it rust to generate a dense rust layer, slowing the entry of air and water into the interior.
(2) Manganese steel: Manganese steel is also known as manganese alloy steel. It is a kind of alloy steel. It is a high-strength steel, mainly used for impact, extrusion, material wear and other harsh working conditions.
